Application filed .Tune 9, 1922.

T 0 all whom/t may concern:

Be it known that I, NARDEN Gr. CAMPBELL, a citizen of the United States,residing at Mason City, in the county of Mason and State of Illinois,have invented new and useful Improvements in Broeders, of which thefollowing is a specification. v

This invention relates to improvements in houses for fowls and the like,the general lobject of the invention being to provide a movablelpartition for varying the size of the receiving compartment of thehouse so as to regulate the temperature therein.

Another object of the invention is to provide means for supporting thepartition in its adjusted position.

This invention also consists in certain other features of constructionand in the combination and arrangement ofthe several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, re` ference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which n Figure1 is a front view of a house constructed in accordance with myinvention.

Figure 2 is an end view.

Figure 3 is a longitudinal sectional view.

Figure 4 is a transverse section. f

Figure 5 is a fragmentary view of the rear of the device showing theVentilating means. l

Figure 6 isa perspective view of one of the cross pieces 12.

Figure 7 is a perspective view of oneof the doors.y

In these views 1 indicates the side walls of the building which may beof any desired size and type, the walls being formed with the usualdoors and windows, though I prefer to provide the doors with woodenparts 2 and parts 3 formedl of galvanized iron and wire mesh, the parts2 sliding in grooves in the door frame and operated by f chains 4 sothat the door openings may be entirely closed by the galvanized ironpart and the wooden part or left open with the open part covered by thescreen.

The floor 5 is movably supported by the Serial No. 567.085.

chains 6 which are connected to the corners of the floor and pass-oversuitable pulleys 7 to a shaft 8 which is rotatably supported in thebuilding and is provided with handle 9 for rotating it and with ratchetmechanism 10 for preventing retrograde movement thereof.

By this arrangement of parts the floor can bel raised and lowered so asto vary the space within the building and thus regulate the temperature.For instance, on a cold night the floor would be raised to make thespace occupied by the chickens small so that the heat from the bodieswould hold the restricted space at the proper temperature. During thedayl the floor would be lowered so as to give the chickens more room andto lower the temperature by increasing the space to be heated.

Besides the ratchet means I may provide means for holding the floor inadjusted position, such means consisting of racks 11 placed along thewalls and cross pieces v12 having beveled ends for engaging the rackteeth and upon which the floor rests when said pieces are in position.

The invention may be used with heated buildings,`as shown inthedrawings. The lamp is shown at 13 and is pivotally supported in thesupport 111. The chimney 15 of the lamp extends into an elbow 16. 'Apipe 17 connects this elbow with a heating drum 18 and a pipe l19 leadsfrom the drum to the outside of the building. A damper 2O is placed inthe pipeline to control the passage of heat. The drum must be placedabove the highest point that the floor is to occupy so that said drumwill al vays rcinain in the occupied space.

I may also provide Ventilating means for the device and in this case thebuildingis provided with air holes 22 which are located above thehighest point which the floor will reach and a gate 23, having per-.orations therein, is adapted to control the passage of air through saidholes.

It is thought from the foregoingdescription that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat suehehanges fall With` in the seopeoi the appended claim. /Vhat I'Claim is A building `oi: the class described compris- 5 ing a verticallymovable floor, a shaft, means for rotating the saine, chains connectingthe cross Apieces havingbeveled ends for engag- 10 ing the racks. andupon which the Hoor rests.`
